ISO 10297 pdf download Gas cylinders — Cylinder valves — Specification and type testing
This International Standard specifies design, type testing and marking requirements for:
a) cylinder valves intended to be fitted to refillable transportable gas cylinders;
b) main valves (excluding ball valves) for cylinder bundles;
c) cylinder valves or main valves with integrated pressure regulator (VIPR);which convey compressed, liquefied or dissolved gases.NOTE 1 Where there is no risk of ambiguity, cylinder valves, main valves and VIPR are addressed with thecollective term “valves” within this International Standard.
This International Standard covers the function of a valve as a closure.
This International Standard does not apply to
– valves for cryogenic equipment, portable fire extinguishers and liquefied petroleum gas (LPG), and
quick-release valves (e.g. for fire-extinguishing, explosion protection and rescue applications), nonreturn valves or ball valves
NOTE 2Requirements for valves for cryogenic vessels are specified in ISO 21011 and at a regional level e.g. inEN 1626. Requirements for LPG valves are specified in ISO 14245 or SO 15995. Requirements for quick-releasevalves are specified ISO 17871. Requirements for valves for portable fire extinguishers at a regionalevel are specified e.g. in EN 3 series. Requirements for non-return valves and ball valves might be specified ininternational/regional standards.
NOTE 3Requirements for manufacturing tests and examinations of valves covered by this internationaStandard are given in ISO 14246.
NOTE 4Additionalrequirements for VIPR are specified in 1SO 22435 for industrial applications or ISO 10524-3for medical applications. Additional requirements for residual pressure valves with or without a non-returrfunction are specified in ISO 15996.Additional requirements for pressure-relief devices might be specified ininternational/regional regulations/standards.
NOTE 5Additional specific requirements for valves for breathing apparatus at a regional level are specifiede.g. in EN 144 series. Additional specific requirements for quick-release valves for fixed fire-fighting systems arespecified in ISO 16003 and at a regionallevel EN 12094-4.
